Abstract

Adaptive filters are presented for improving the wavelength detection accuracy of FBG sensors within a sensing system which use tunable laser source. Simulation results demonstrated that by using this technique the Bragg wavelengths of the FBG sensors can be accurately detected. In addition, the filter with NMLS-OCF adaptive algorithm performs faster convergence than the other algorithms.
